The present invention relates to flame-retardant compositions containing: A. 65 to 99.998 wt. % polycarbonate, B. 0.001 to 1 wt. % of an organic flame-retardant salt selected from the group consisting of alkali and alkaline-earth salts of aliphatic and aromatic sulfonic acid, sulfonamide and sulfonimide derivatives and mixtures thereof, and C. 0.001 to 1 wt. % of one or more bromine-containing flame-retardant additives, characterised in that that the overall composition contains 100 ppm to 1000 ppm bromine.
摘要:
The present invention relates to flameproofed, UV resistant polycarbonate moulding compositions with good melt stability and a high proportion of free, reactive UV absorbers, wherein the polycarbonate compositions compriseA) at least one polycarbonate with an average molecular weight M w of 18,000 to 40,000,B) at least one alkali or alkaline earth salt of an organic flame retardant consisting of diphenylsulfone, alkali or alkaline earth diphenylsulfone sulfonate and alkali or alkaline earth diphenylsulfone disulfonate, andC) one or more reactive UV absorbers, and wherein B) comprises diphenylsulfone in a proportion of 1.10 wt. % to 2.50 wt. %, based on the total mass of component B).
摘要:
The present invention relates to flameproofed, UV-resistant polycarbonate moulding compositions having improved flame retardancy and a low incorporation of the UV absorber into the polymer chain and a resulting higher relative viscosity compared with the polycarbonates having increased incorporation of UV absorber, wherein the polycarbonate compositions comprise A) at least one polycarbonate having an average molecular weight Mw of from 18,000 to 40,000 g/mol, B) one or more reactive UV absorbers and C) at least one alkali metal or alkaline earth metal salt of a fluorinated organic acid, and C) has a content of free sulfate of less than 0.007 wt. % and a content of free fluoride of less than 0.017 wt.%, in each case based on the weight of C).

摘要:
A modular switching network node for a communications network, i.e., an industrial communications network, where the modular switching network node comprises a switching network node base unit and at least one port module, the at least one port module comprises at least one connection interface for coupling to the communications network, and where the modular switching network node is configured to forward communication data over one of the connection interfaces of the modular switching network node to at least one additional connection interface of the modular switching network node. The switching network node base unit is configured such that at least one of the port modules is swappable for a functional module to expand the functionality of the switching network node.

A valve device for an internal combustion engine includes a housing with an inlet and an outlet, a passage opening which fluidically connects the inlet with the outlet, a first valve-closing member which controls the passage opening, an actuator, a valve rod on which the first valve-closing member is arranged, a stop element, a spring surrounding the valve rod, and an element. A first end of the spring is supported against the first valve-closing member, and a second end of the spring is supported against the stop element. The element substantially surrounds the spring. The element comprises a first lateral surface and a second lateral surface in mutual engagement with each other. The first lateral surface abuts against the first valve-closing member and is movable therewith. The second lateral surface abuts against the stop element. The first valve closing member moves relative to the stop element.

A head support for a backrest of a motor vehicle seat, which can be folded out of an upright use position into a cargo position directed in driving direction. The head support is mounted to be foldable toward the front side of the backrest between an upright operative position is in the use position, and a folded down inoperative position when the backrest is in the cargo position, around a horizontal head support spindle of a holder arranged at the backrest and carries the head support the head support spindle extends transverse to the driving direction. The holder is lowered completely or partially into a lowered position in the backrest in the inoperative position of the head support and can be raised from the lowered position into the raised position of the operative position.
